Cat ELC (Extended Life Coolant)
Caterpillar provides Cat ELC for use in the following applications:
Heavy-duty diesel engines
Automotive applicationsWhen Cat ELC is compared to conventional coolants the Cat ELC anti-corrosion package is based on a totally different additive system. Cat ELC has been formulated with the correct amounts of additives in order to provide superior corrosion protection for all metals that are in engine cooling systems.Cat ELC extends the service life of the coolant to 12000 service hours or six years. Cat ELC does not require a frequent addition of a SCA (Supplemental Coolant Additive). An Extender is the only additional maintenance that is needed at 6000 service hours or one half of the ELC service life.Cat ELC is available in a 1:1 premixed cooling solution with distilled water. The Premixed ELC provides freeze protection to −37 °C (−34 °F). The Premixed ELC is recommended for the initial fill of the cooling system. The Premixed ELC is also recommended for topping off the cooling system.ELC Concentrate is also available. ELC Concentrate can be used to lower the freezing point to −52 °C (−62 °F) for arctic conditions.Containers of several sizes are available. Consult your Caterpillar dealer for the part numbers.Note: Caterpillar developed the EC-1 specification. The EC-1 specification is an industry standard. The EC-1 specification defines all of the performance requirements that are needed for an engine coolant to be sold as an extended life coolant for Caterpillar engines. Cat ELC can be used in most OEM engines of the following types: diesel and gasoline. Cat ELC meets the performance requirements of "ASTM D4985" and "ASTM D6210" for heavy-duty low silicate antifreeze/coolants, but does not require treatment with conventional SCA. Cat ELC also meets the performance requirements of "ASTM D3306" for automotive applications.
